F4+4, you can clean it with about anything & can use rainx on it which shouldn't be used on other windshields because it will damage them. They are super clear and are very scratch resistant where the stock one seemed to scratch if I looked at it funny. I bought the vented model and am happy with it as it provides better protection from the wind & rain than the stock one did. Had to call F4 customs with a question when I was installing it & the person answering the phone was polite & answered all my questions. Regardless of which windshield you buy, go to F4's website & watch the installation video a couple times before installing your new shield as there is lots of good info which will save you time & problems.
